The porch on the doorbell camera is empty. But in the glass of the front door, someone is standing right there, and they turn to look at the camera. Fixed-camera 'caught on doorbell' horror is a breakout AI format this autumn, and it works because the camera never moves.
Why it is trending
With Halloween days away, short creepy 'found footage' clips are surging on TikTok and Shorts; doorbell and CCTV framing makes AI video feel unsettlingly real.
The master prompt
Copy it as it is, or change the parts in [BRACKETS] to make it yours.
Create a 20-second vertical (9:16) found-footage clip from a fixed doorbell security camera at 3:07 a.m. The porch looks empty, but a tall figure appears only in the reflection on the glass panel of the front door. Creepy, quiet, slow-burn; no gore. CAMERA: fixed wide fisheye doorbell view from beside the door, slightly high angle, looking out at the porch steps, a doormat, a potted fern and the dark street. Night-vision grey-green tint, slight compression noise, subtle infrared glow on close objects, NO camera movement at all, no on-screen text or timestamp. REFLECTION: the right edge of the frame shows part of the door's glass panel, which reflects the porch. FIGURE (reflection only): very tall, thin, in a long dark coat, face hidden in shadow except for two faint pale eye-glints. SETTING: suburban porch, wooden steps, a hanging porch lamp that flickers once, mist drifting over the empty street. [00:00-00:05] NOTHING — The porch is completely still. Mist drifts across the street. A moth circles the porch lamp. [00:05-00:09] THE GLASS — In the door's glass reflection, a tall dark figure is now standing on the doormat. On the real porch, the doormat is empty. [00:09-00:13] THE LAMP — The porch lamp flickers once; for a single frame the figure in the reflection is closer to the glass. [00:13-00:17] IT TURNS — The figure in the reflection slowly turns its head toward the doorbell camera; the two pale eye-glints catch the infrared. [00:17-00:20] GONE — Static flicker; the reflection is empty again. On the real porch, the potted fern slowly rocks as if someone just walked past it. Cut to black. SOUND: low electrical hum of the camera, distant wind, a soft creak of a porch board at 00:06, a faint muffled knock at 00:18, then silence. RULES: no gore, no jump-scare faces, no text, no logos; the figure never appears outside the reflection; camera is perfectly still.
Short version (for apps with a character limit)
9:16 found footage from a fixed fisheye doorbell camera at night, grey-green night vision, compression noise, no camera movement, no text. The porch is empty, but in the reflection on the door's glass panel a very tall thin figure in a long dark coat stands on the doormat. The lamp flickers and the reflection is suddenly closer. It slowly turns its head to the camera, pale eye-glints catching the infrared. Static flicker — the reflection is empty, and on the real porch the potted fern rocks as if someone walked past. Low hum, a creak, a faint knock.

Nothing
The porch is completely still. Mist drifts across the street. A moth circles the porch lamp.
- 00:05-00:09
The Glass
In the door's glass reflection, a tall dark figure is now standing on the doormat. On the real porch, the doormat is empty.
- 00:09-00:13
The Lamp
The porch lamp flickers once; for a single frame the figure in the reflection is closer to the glass.
- 00:13-00:17
It Turns
The figure in the reflection slowly turns its head toward the doorbell camera; the two pale eye-glints catch the infrared.
- 00:17-00:20
Gone
Static flicker; the reflection is empty again. On the real porch, the potted fern slowly rocks as if someone just walked past it. Cut to black.
Keep the characters consistent
Paste this description into every clip so the character looks the same from shot to shot.
The reflection: Very tall, thin figure in a long dark coat, face in shadow, only two faint pale eye-glints visible, seen ONLY in the door glass reflection.
Sound and music
Camera hum, wind, one board creak, a faint knock, then silence.
What to avoid (negative prompt)
gore, monster face close-up, jump scare, camera movement, text, timestamp, logos, daylight
Remix it: ready-made variations
Baby monitor
Fixed night-vision baby-monitor view of an empty nursery; the rocking chair in the corner starts rocking slowly by itself, a toy music box opens and plays, then everything stops when the hallway light turns on. No people, no gore, 9:16.
Elevator CCTV
Fixed CCTV view inside an empty office elevator at night: the doors open on floor 13 to a pitch-black corridor; the elevator lights dim; when the doors close, the mirrored wall shows one extra shadow. No gore, no text, 9:16.
Wholesome twist
Same doorbell-camera setup, but the figure in the reflection turns out to be a tall friendly scarecrow dropping off a basket of Halloween sweets; it waves at the camera and the porch lamp glows warm orange. 9:16.
Tips for each AI model
| Model | What to do |
|---|---|
| Veo 3.1 | Say 'fixed security camera, no camera movement' twice; Veo likes to push in on scary moments. |
| Kling 2.5 | Generate the empty porch as a still first, then use image-to-video so the frame never changes. |
| Grok Imagine | Short, punchy prompts work: use the short version. |
How to make it, step by step
- Lock the frame. Make one still of the porch from the doorbell angle.
- Generate the reflection beats. Animate from that still so the porch stays identical.
- Add camera texture. A light noise filter and a slight fisheye in your editor sell the footage.
- Post it right. Caption it as a story ('my doorbell caught this…') and label it as AI-generated.

Questions
How do I make AI horror feel real?
A fixed camera, night-vision colour, compression noise and slow pacing. What you do NOT show is scarier than any monster.
Is this suitable for YouTube?
Yes. It has no gore or violence. Label realistic AI footage as AI-generated.
Why only in the reflection?
The contradiction between the empty porch and the reflection makes viewers rewatch it to check, which boosts replays.
